Sewage is home to many microbes. Many of these microbes
are the main workers in cleaning up sewage sludge. They eat
the sludge and release carbon dioxide gas,water and trace
minerals. These weird, coiled-shaped microbes live
with other microbes in a culture from sewage sludge.

Weird Shapes

Most bacteria are shaped like short or long rods, spheres
or cork screws. The bacterium shown above is unusual because
it is coiled. No on knows why they grow in coils.

Unknown Bacterium

Like most bacteria in nature, little is known about this
bacterium. We know its shape and where it lives, yet know
one knows what it eats, what microbes it is related to, or
what it does in sludge.
